In pre-trip inspections, what does CDL stand for?

The term CDL stands for Commercial Driver's License. This license is a specific credential that allows individuals to operate commercial motor vehicles (CMVs) such as trucks and buses. The CDL ensures that drivers have met certain federal and state regulations regarding knowledge and skill necessary to safely drive these larger vehicles.

Having a CDL requires passing written tests and skills assessments, which are crucial for promoting safety on the roads. The other options listed refer to terms that are not officially recognized or regulated, making them incorrect. Understanding what CDL stands for is fundamental for anyone training to operate a commercial vehicle, as it also encompasses the laws and requirements related to pre-trip inspections and general driving practices in a commercial context.
